It'll be interesting to see how you go, a few people have gunned for it but Heat Treatments (Skyline GTR) have had a pretty good hold of it for the last 5 years. They've actually developed the car further from when they did the 7.57 @ 191mph in 2006, and only a couple of weekends ago reset the quickest time to a 7.56 @ 184mph on their first run of an event before the it was rained out so the target could prove to be a moving one.

We will make the best we can, but our cars uses 4cylinder engines not 6cylinder.
If we specialy built a 6cylinder then the power will be x 50%. If we manage to have from a 2ltr 2000cc engine soon close to 2000hp then a same level tuning of a 6cylinder engine must have 3000hp.
(we built as we speak a 6cylinder engine close to our expectations)
also Trasmitions and 4wd systems bolted on the stock location, nothing modified and cutted.
But for these kind of situations we recently built a dragmachine equiped with 4 cylinder nitromethanol 1998cc engine. Magnesium gearbox with airshifter and engine aiming more than 1600+ hp at the final stage and 2hp per 1kgrm ratio. If someone drive this thing to a straight line we think will reset the 7.57 just with a little 4cylinder nitromethane engine. We will see soon.

Hi Spyros,
I was visiting the brand new Drag arena here in Sweden, Tierp Arena, and found a car from Germany running one of your Turbos. Nice to see your stuff out there
If you are looking for a place to test your cars, you need to go to this new Drag strip here in Sweden. The surface is amazing to say the least. They ran a TF @ 3,95s!!!! A guy from the states with his TF. So for testing/running your cars at max, this is the place.
Good luck!

Hi
We decide to test stage 3 cams to an engine that can support the high acceleration of these cams. We knew that this engine is junk because was made before 4-5 years. With low Cr ratio and 2.2ltr stroke with terrible rod/stroke ratio. The only part good was the cylinder head that have berilium parts and good valvetrain to support stage3. Also we knew that the turbo is not to big to support high rpms and the stroke to rod/ratio also, even the intake manifold couldn’t support them.
These cams are designed to work to more efficient engines and produce power till +12.000 rpms easy. The turbo is only 158lbs/min so we expected to finish little more than 1730hp, but I run out from fuel injectors. We have primary 160lbs and secondary 680lbs.
We had 1690hp and 1149lb/ft at 52psi running plain methanol. No nitromethane used as we just wanted to see the cams how they perform and we also hadn’t bigger injectors to fit.
So these cams is not that they deserve, and we will test them soon to more efficient engines that are designed to work. If u notice above the 8000rpms the power falls, the backpressure gauge show us that the turbine housing was to small for such power although the 94mm turbine wheel is so efficient, we thought that 53lbs at 66% efficiency that the turbine flow is rated was capable producing 1700hp. Also our dyno cant suport more torque both of axles vs rpms.
Coming with more tests.
